`SPECIFICATION forming part of Letters Patent No. 258,250, dated May 23,1882.

Application filed May 14, 1881. (No model.)

lb all whom it may concern zen of the United States, residing at No. lMiddagh street, Brooklyn, in the county of Kings vand State of New York,have invented certain new and useful Improvements in a Three-Part (moreor less) Automatic Gonical Valved Pump; and I do hereby declare thefollowing to bea full,`clear, and exact description of the invention,such aswill enable others skilled in theart to which it appertains tomake and use the same, reference being had to the accompa- `nyingdrawings, and to the letters or gures of reference marked thereon, whichform a part of this specification.

MyY invention relates primarily to pumps, though it is applicable inother'situations for forcing water for the propulsion of ships,canal-boats, and the like, as well as for elevating water or forthrowing it in streams. Y

Itconsists in devices and combinations hereinafter fully set forth andspecifically claimed.`

the art.

In my improved apparatus I have succeeded in giving to a. column ofwater a. continuous movement without any sudden impulse or shock to thevalves or to any part of the apparatus, and without the necessity ofusing any checkvalves. This apparatus is represented in the accompanyingdrawings, in which- Figure l shows a central longitudinal section of thefixed and movable parts of the tube or cylinder, with the operatingmechanism and Fig. 2 shows an additional construction in which myinvention is carried forward in its application to other situations, ashereinafter fully explained.

In the drawings the fixed sectionsof the tubular construction are shownat A As attached to any suitable support by ears B 13 through which passsuitable screws or bolts.

v Upon the ends of these lixed sections, which VBe it known that I,ENOCH OSGOOD, a cititubes O and intermediate packing, b. These parts areso arranged as to permit the same amount of motion to all the movableparts .0. As shown, these parts are three in number; but in practice twoor more may be used. I have shown the connections I3 B only upon theupper and lower fixed sections; but it will be understood that theintermediate sections are connected iirmly to a base or standard in likemanner. It will be observed that the movable parts are the larger andwork on the outside of the fixed parts, the fixed parts being plaincylindrical tubes. l

Within the movableparts C, midway oftheir length, I place valves D D,hinged opposite each other and adapted to close upon the ant nularvalve-scatf, the inner periphery of which is of the same diameter as thetubes A. The valves I) I) are formed out of sections of tubularmaterial, of metal, in any suitable manner.

These sections are made, as shown in the gn. win

be understood that when these valves are open they lie against the Wallot' the tubular part,'in which they are pivoted; but as their shapecorresponds in contour to that ot' the wall of the, tube and theirthickness does not exceed in any degree obstruct the ilow of the water.Their peculiar action in connection with the special construction andoperation ofthe movable sections will be. referred to hereinafter;

The movable sections are connected to a-shaft, A

O, by means of cranks E and links F. These cranks are set upon the shaftat different an"- gles, and the arrangement of these ,cranks4 `is suchas to advance and retract the sections IOO successively, so that theirposit-ion at one point i. i

in the revolution of the sha-ft O wouldv be'as l that ofthe fixed part,when open they do not l shown in Fig. 1, where the upper valves areclosed, the middle half open, and the lower quite open, in whichposition the upper pair of 'valves would be in action, forcing thewater,

' more slowly than the stream itself, opens with a gradual movement, andis then drawn back with the valves lying against the walls of thetubular section. As they reach the limit of their backward movement thecontinuous revelution of the shaft arrests each section and causes itgradually again to advance as the shaft carries the arm past thedead-center. The motion of the section in this revolution of thecrank-arm, being little slower at flrst, gradually overtakes the currentof water, and by pressure against it closes the valves, but at the sametime closes them by a gradual pressure, which pressure increases as theforward motion of the section increases, and the same action is followedby all the sections and their valves in succession. The valves are sohung as to move inward when relieved of the press- `ure of a current ofwater moving past them, so that they close automatically by their ownweight, or with no other pressure than that afforded by the stream ofwater against which they move. It will be observed, therefore, that thisform of valve is specially adapted to the special construction ot' thepump. The valve moves only through one-eighth of a circle. It is adaptedalso to the larger and smaller sections, so that it leaves the largertube unobstructed and a passage-way through it equal in diameter to thatof the fixed sections A. Manifestly the valves D might be hinged in thesections A, but with less favorable results. Itwill be readilyunderstood that other means may be used in the place of the shaft O,with its cranks and connectingrods F. I have shown these as being welladapted to the valves, it being necessary only that the section shouldreciprocate in proper order, so that the valves of one section shouldtake hold of the column'of water at the proper instant when the valvesof the other sections are opening or moving back in a fully openedposition. The column of water is never arrested in its motion with thisproper arrangement ofthe movable sections, and there is no shock to anyof the moving parts of the mechanism.

I have described the device as specially applicable to pumps for forcingor raising water; but it is also applicable for the propulsion of shipsor canal-boats..

For the propulsion of ships or any kind of water-craft the tubularstructure may be 1ocated in the bottom, by the side ofthe keelson;

or one may be used upon each side of the keelson. It will be understoodthat the tubein such a case should extend the entire length of the shipand be provided with an opening through the ship, both at the bow andstern, so that the water could be drawn in at the bow and forced out atthe stern. The special advantages which arise out of this mode ofpropulsion need not be herein fully described. The principle is that thewaterl is drawn in from about the bows and heaped up at the stern,reversing the position of the water as it impedes the progress of thevessel in sailing. For use in canal-boats its location at the greatestdepth of the craft renders it particularly applicable, since it can beused without any disturbance of the water, which occasions the washingof the banks. For use upon watercraft it may be duplicated in the mannershown in Fig. 2, and be provided with double catches, so that the movingtube represented in said figure may be made to operate in either of twodirections. The valves D D are pivoted upon opposite sides ofthevalve-seatf, and are provided with catches I I, pivoted in lugs and onthe outside of the tube-section, and connected by an arm, H, so thatboth valves may be thrown into gear with the valves D when. open on oneside, while the valves on the other side of the valve-seat are left freeto operate.

In order to reversethe apparatus, and thereby the direction of thecurrent and the movement of the ship, itis only necessary to cha-nge theposition of the catches.

A device of this sort for propelling ships does not interfere with thesailing qualities of the ship.

I am aware that a moving section has been heretofore described carryinga valve and acting like a plunger, as in the patent of Tapley, No.11,704, September 19, 1854; and Iam also aware of the form of valveshown in the patent of Dodge, No. 9,706, May 10, 1853, and I desire tohave my claims understood as limited in'view of what is shown in saidpatents.V

A device forforcing water, consisting of the fixed and movable sections and devicesfor operating the movable sections, in combination with the doublevalves D D and valveseats, the sections being adapted to operatesuccessively, substantially as described.
